.Sh DESCRIPTION
.Nm
takes a principal database in a specified format and converts it into
a stream of Heimdal database records. This stream can either be
written to standard out, or (more commonly) be propagated to a
.Xr hpropd 8
server running on a different machine.
.Pp
If propagating, it connects to all
.Ar hosts
specified on the command by opening a TCP connection to port 754
(service hprop) and sends the database in encrypted form.
.Pp
Supported options:
.Bl -tag -width Ds
.It Fl m Ar file , Fl Fl master-key= Ns Pa file
Where to find the master key to encrypt or decrypt keys with.
.It Fl d Ar file , Fl Fl database= Ns Pa file
The database to be propagated.
.It Fl Fl source= Ns Ar heimdal|mit-dump|krb4-dump|kaserver
Specifies the type of the source database. Alternatives include:
.Pp
.Bl -tag -width mit-dump -compact -offset indent
.It heimdal
a Heimdal database
.It mit-dump
a MIT Kerberos 5 dump file
.El
+.It Fl k Ar keytab , Fl Fl keytab= Ns Ar keytab
The keytab to use for fetching the key to be used for authenticating
to the propagation daemon(s). The key
.Pa hprop/hostname
is used from this keytab.  The default is to fetch the key from the
KDC database.
.It Fl R Ar string , Fl Fl v5-realm= Ns Ar string
Local realm override.
.It Fl D , Fl Fl decrypt
The encryption keys in the database can either be in clear, or
encrypted with a master key. This option transmits the database with
unencrypted keys.
.It Fl E , Fl Fl encrypt
This option transmits the database with encrypted keys.
.It Fl n , Fl Fl stdout
Dump the database on stdout, in a format that can be fed to hpropd.
.El
.Sh EXAMPLES
The following will propagate a database to another machine (which
should run
.Xr hpropd 8 ) :
.Bd -literal -offset indent
$ hprop slave-1 slave-2
